So, I immediately downloaded the update through Wi-Fi. The size of this update was 200MB. The look and feel were pretty cool, which made me delete the Go Launcher Ex as well as the Go Locker.

Everything seemed fine until I clicked on Google search and found out that it wasn't getting connected. I was shocked. At this point, my immediate thoughts were, ''Oh damn! By downloading the ICS update, have I ruined this phone?''
After spending a lot of time pondering over this, I came across this person, who shared a similar experience. He also revealed a procedure, following which my Google search and Internet started working.

The Procedure :
A common observation: Neither Google search nor the Internet does work after the Ice cream Sandwich update. You need to manually fix it.
Here’s how you can do it:
Settings — More — Mobile Networks — Access Point Names — Options Reset to Default.
Turn off phone for 1 minute — Restart.
Settings — Applications — Select ALL tab.
Find Internet Application and Clear Data.
Find Google Search Application and Clear Data.
Turn off phone for 1 minute — Restart.
Wait for the home screen to refresh a couple of times and try again.
Eureka! This fixed it for me.
